Build Arm flashlight +Antistatic strap for computer repair

[St.Alia-Of-The-Knife]

Alright, i have an idea for my science project this year
We have to build/invent something that will help out with common tasks, and it must include simple electronic circuits.

I have an idea, its basically a circular flashlight(like those in surgery rooms to prevent casting shadows) attached to the arm so it wouldnt use a hand to hold it. But in the same time, its a antistatic wrist strap. I do work a lot inside my case which has a lot of dark corners and small spaces and the lighting is a huge problem. I also do some motherboard soldering which is kinda like delicate surgery on a computer

I found this hexlight thing which is similar to what i want to build

so please leave your opinion and maybe suggest me a few sites and information i need to know to build it

build one that has lights on fingertips.
or buy a screw driver which has a light at the tip (i have one)

Hmm... a light at the tip of the screwdriver should be useful

1) Check for patents. Given that you've found something exactly like you are describing, you should be aware of patents that you cannot infringe upon (depending upon project scale).
2) Search for the "joule thief." It is a circuit that maintains a relatively constant voltage, even as batteries begin to die. It's used in a lot of projects. I originally read about it on hackaday: http://hackaday.com/
3) Anti-static devices are easy. If you're going for a wrist strap include a layer of metal foil and solder a wire with an aligator clip to it. ASDs just make sure your potential matches that of the surface you're contacting, and a direct connection does that every time.


I wish you the best of luck, but fear this project is an extreme niche. Anyone capable of soldering will have a good bench setup with clamping. Anyone who uses computers likely has an ASD. A flashlight is already built into some tools, as several of my peers have stated. It is likely still worth exploring purely for knowledge, but may not be a practical project.
